DETACHAIBLE RUNNER FOR FOLDING GO-CAR'IS.

Specification of Letters Patent.

Application filed May 12, 1911.

Patented Feb. 13, 1912.

Serial No. 626,739.

To all whom it may concern:

Be it known that we, WILLIAM H. JoY, MARK H. SMITH, and FRANCIS KORFF,citizens of the United States, residing at Lansing, Michigan, haveinvented certain new and useful Improvements in Detachable Runners forFolding Gro-Oarts, of which the following is a specification.

This invention relates to improvements in detachable runners forcarriages.

Our improved detachable runner is especially designed by us for use onfolding gocarts 0r carriages, of the type in which the wheels fold underthe body when the carriage is collapsed, although it is desirable forand adapted for use in various other types.

The main objects of this invention are to provide an improved detachablerunner for carriages which can be attached or removed without the use oftools and which is very secure when attached.

Another object is to provide an improved detachable runner for carriageswhich may be readily adjusted to carriages of different sizes, so thatgreat accuracy in manufacturing is not required.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

We accomplish the objects of our invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of our invention is clearlyillustrated in the accompanying drawing, forming a part of thisinvention, in which Figure I is a detail side elevation of a structureembodying the features of our invention, a pair of carriage wheels withtheir connecting bar being shown in connection therewith to illustratethe manner of applying the runner to the wheels, the locking togglebeing shown in its released position by dotted lines. Fig. II is aninside perspective view of our improved detachable runner. Fig. III isan enlarged cross section of the runner taken on a line corresponding toline 33 of Fig. II.

In the drawings similar reference characters refer to similar partsthroughout the several views.

Referring to the drawings, 1 represents ward end to form the nose 6. Therear end of the shoe portion of the runner is curved up at 7 The plates5 co-act with the vertical arm 8 of the runner in forming seats for thewheel as shown.

The runner is clamped and locked upon the wheels by means of anadjustable attaching member for one wheel comprising a link 9 pivoted tothe vertical arm 8 of the runner at 10, the link being ofiset at itsouter end 11 to receive the shank of the wheel engaging hook 12. Theshank of the hook 12 is threaded and is adjustably secured to the linkby means of the nuts 18. A clamping toggle is provided for the otherwheel and consists of the link 14 mounted on the pivot 10. A lever 15 ispivoted to'the link 1d at 16; and the wheel engaging hook 17 is pivotedto the lever 15 at 18. The hook 17 is adapted to engage the felly of thewheel when the lever 15 is swung up to the position indicated by dottedlines in Fig. I, or as shown in full lines in Fig. II.

To look the toggle and clamp the wheel, the lever 15 is swung downagainst the runner as is shown by full lines 1n Fig. I; this appliestension to the runner and clamps and locks the parts in place. The hook12 is adjusted to secure the desired clamping tension when the toggle islocked. By thus arranging the parts we secure a structure which may bereadily attached or detached, and which, when attached is very secure.Further, it is adjustable so that it may be applied to carts differingquite materially in size, that is, in the space between the wheels, andgreat accuracy in manufacturing either the carriage or the runners isnot required.

Our improved runner when attached is neat in appearance and can bereadily attached or detached without the use of tools after theadjustable member has been adjusted t0 the particular carriage on whichtherunner is to be used. Where the runner is made especially for aparticular gocart no adjusting device is needed.

We have illustrated and described our improvement in a simple andeffective em bodiment thereof. We are aware, however, that considerablevariation and construction of details are possible, but as suchvariations will no doubt be obvious to those skilled in the art to whichthis invention relates, we have not attempted to illustrate or describethe same therein Having thus described our invention, what we claim asnew and desire to secure by Letters Patent is:
